It is applied to three-phase squirrel-cage inductive motor of AC 50Hz with rated voltage of 380V, to start the motor with reduced voltage in infrequent operation condition. It reduces the voltage through the transformer in order to reduce the starting current of the motor and the negative impact on the power transmission network.

Working conditions

1.Ambient air temperature: -5°C~+40°C, the highest monthly mean temperature should not exceed +30°C;

2.Altitude for installing place should not exceed 2000m;

3.When the ambient air temperature is +40°C, the relative humidity should not exceed 50%, and it allows higher relative humidity under lower temperature. Max average humidity in the dampest month is 90%, meanwhile the lowest average temperature of this month is + 25°C, and condensation on the product surface caused by temperature change should be taken into consideration.
